Re-enable gravity when it has stopped its' collision with an object

hello,

my script disables the gravity of my enemy gameobjects once it collides with my tower gameobject which allows the enemy to "climb the tower". However, if the enemy were to stop colliding or touching the tower gravity is still disabled and the enemy just floats around the scene. I want gravity to be re-enabled so they aren't just floating in space.

Here's my script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ClimbTower : MonoBehaviour {
6.     GameObject gameObjectEnemy;
7.     DestroyObject destroyObject;
8.  
9.  
10.  
11.     bool climbTrue;
12.  
13.    
14.     float tmpSpeed;
15.     [SerializeField] float climbSpeed = .09f;
16.  
17.  
18.  
19.  
20.     private void Update()
21.     {
22.         Move();
23.        
24.         Debug.Log(climbTrue);
25.     }
26.     public void OnCollisionEnter2D(Collision2D collision)
27.     {
28.         if (collision.gameObject.tag == "Tower")
29.         {
30.             climbTrue = true;
31.             gameObject.GetComponent<Rigidbody2D>().gravityScale = 0f;
32.         }
33.      
34.  
35.     }
36.  
37.    
38.  
39.  
40.     public void Move()
41.     {
42.        
43.         if (climbTrue)
44.         {
45.             transform.Translate(0f, climbSpeed, 0f);
46.         }
47.  
48.     }
49.  
50.    
51.  
52.  
53. }

 

Can't you just use OnCollisionExit2D?

 

haha definitely. i forgot/haven't used that one. I'll try it out, thanks man.
